Summary

Out-of-bounds read in `bytes_helper` public safe functions

Details

The bytes_helper module contains multiple public functions (into_arr4(), into_arr2(), u8_from_le_bytes()) that use slice.get_unchecked(pos..pos + N) without verifying that pos + N <= slice.len(). These are public safe API functions, allowing any caller to trigger undefined behavior by passing invalid positions.

For example, calling into_arr4(&data, 10) where data is a 3-byte slice causes an out-of-bounds access since position 10 exceeds the slice length.
